With recent successes of laboratory, inatmosphere, and space demonstrations of free-space
optical communications, there is no doubt that the technology is ready for operational …

IMPLICATIONS: Preliminary data, although limited, suggest that ultrasound-guided imaging
during regional blockade may improve outcomes and decrease complications. Educational …

BACKGROUND: Regional anesthesia (RA) provides excellent anesthesia and analgesia for
many surgical procedures. Anesthesiologists and patients must understand the risks in …

This article reviews current evidence for the efficacy of adding novel analgesic adjuncts to
brachial plexus block, the goal of which is to prolong analgesic effect without the disadvantage …

Quantum-mechanical calculations of the mean-square fluctuation spectra in optical homodyning
and heterodyning are made for arbitrary input and local-oscillator quantum states. In …

The psychometric properties of pain intensity scales for the assessment of postoperative
pain across the adult lifespan have not been reported. The objective of this study was to …

Study Objective: To evaluate the validity and reliability of an objective scoring system, the
Post-Anesthetic Discharge Scoring System (PADSS), which was compared against existing …

Optical communication over the clear atmosphere provides a means for high data rate
communication (gigabits per second) over relatively short distances (kilometers). However, …

Background Aspiration of gastric contents can be a serious perioperative complication,
attributing up to 9% of all anesthesia-related deaths. However, there is currently no practical, …

IMPLICATIONS: Real-time ultrasound imaging during supraclavicular brachial plexus blocks
can facilitate nerve localization and needle placement and examine the pattern of local …
